Abstract
The invention discloses an improved microwave radiation device which is provided with a cylindrical shell (1), wherein radiating fins (2) are radially and uniformly distributed on the shell surface in radial direction (1), a helical antenna (3) and a lens (4) are sleeved on a coaxial line in the shell (1); one end of the helical antenna (3) is a convexity, and the other end of the helical antenna is concavity; and the lens (4) is arranged on external side of the concavity of the helical antenna (3). Spherical electromagnetic waves converted into linear waves by the invention are transmitted outwards by the helical antenna (3). The waves bunch through the lens and form a high-energy microwave beam far field to radiate human bodies to generate a great amount of heat, so that tumor bodies can be quickly heated to realize partial and deep hyperthermia on the tumors and produce the whole-body hyperthermia effect, thereby achieving favorable treatment effects on malignant tumors, AIDS, hepatitis C and virus flu.
Description
Affiliated technical field
The present invention relates to a kind of medical apparatus and instruments, relate in particular to a kind of microwave radiation device of microwave heat therapeutic equipment with microwave pack function.
Background technology
Utilize the bio-heating effectiveness of microwave to treat the human diseases history of existing nearly half a century.Past people microwave principle commonly used is made into the device of external heating or body cavity internal heating, for example microwave radiometer is designed to aciculiform or is close to the hood-shaped antenna of body surface, treats malignant tumor and other disease.Along with science and technology development, there is enterprise to produce the micro-wave therapeutic equipment that power surpasses high-power, the far field heating of 500W in recent years, be used for the treatment of human malignant tumor.The UHR-2000 type microwave diathermy machine produced of the WB-1 type microwave diathermy machine produced of Chinese Shanghai China source thermotherapy technology company limited and Hunan China China source armarium company limited for example.Deep thermotherapy and the whole-body hyperthermia heated and can be used for tumor in high-power far field.But the key technology of equipment is to improve the microwave radiation device with microwave pack function of organizing the depth of penetration heating and the efficient of heating of microwave.But known microwave radiation device generally, and the microwave of its generation has only 3-5cm to the depth of penetration heating of tissue, is difficult to reach the purpose that deep tissue and trunk blood are heated to treat.
Summary of the invention
The technical problem to be solved in the present invention is, for high-power far field microwave heat therapeutic equipment designs a kind of improved microwave radiation device with efficient microwave pack function.Use microwave that this device produces can both obtain obvious raising, thereby can realize truly microwave deep thermotherapy and whole-body hyperthermia to the depth of penetration heating of tissue and energy density and to the heats of tissue and blood.
Technical solution of the present invention is, designed this microwave radiation device with efficient microwave pack function referring to Fig. 1, has barrel-type casing 1, and the drum surface of this housing 1 radially is evenly distributed with a plurality of fin 2 radially.Its improvements are that coaxial line is equipped with a helical antenna 3 and lens 4 successively in the described barrel-type casing 1.Described helical antenna 3 an axial two ends wherein end are convex surface, and the other end is concave surface, and described lens 4 promptly place described helical antenna 3 to be the concave surface one end outside.
When using, adopts microwave radiation device of the present invention the microwave source of 433MHZ microwave source or 915MHZ, output 500-2000W.The microwave that sends from microwave source arrives this device through transmission cable, and the microwave that is sent by the above-mentioned helical antenna 3 of this device is radiated human body on the therapeutic bed through lens 4 packs.Again by computer acquisition to body temperature and other vital sign information as calculated with analyze after, the instruction microwave source is regulated microwave output power and is changed the therapeutic bed speed of moving body, reaches the control purpose that effectively treatment temperature and preventing is excessively heated and other untoward reaction occurs.
The invention has the beneficial effects as follows,, after the sphere electromagnetic wave that is sent by magnetron that transmission cable is sent to converts straight wave to, outwards launch by its helical antenna 3 again by the above microwave radiation device of the present invention that constitutes.When the lens of microwave by irradiator below, the microwave pack also forms high-energy microbeam far-field radiation and enters human body.When microwave ran into polar molecule in human body, such as blood, molecular friction and molecular motion can appear in tissue fluid etc., produce a large amount of heats then.The microwave heat therapeutic equipment that is equipped with microwave radiation device of the present invention promptly can be aimed at the tumor locus far field irradiation of this human body, and tumor tumor body temperature degree is raise rapidly, generally wants projecting normal structure 3-7 ℃, so at once the part and the deep thermotherapy of tumor.When the mobility Radiation sickness person trunk of this microwave heat therapeutic equipment far field, also can heat because of deep trunk blood in large tracts of land body surface blood capillary and the body, through the blood circulation, cause the whole body fervescence and produce the whole-body hyperthermia effect.Medical research both at home and abroad is verified, and whole-body hyperthermia all has goodish therapeutic effect to malignant tumor, acquired immune deficiency syndrome (AIDS), hepatitis C, viral influenza.
